CPT® Code 27727

The CPT® Code 27727 refers to the surgical procedure for the repair of congenital pseudarthrosis of the tibia. This condition is characterized by a defect in the bone that can present in various forms, such as cystic, sclerotic, or dysplastic. The term "pseudoarthrosis" translates to "false joint," indicating that there is abnormal movement at the site of the defect, which can lead to instability and deformity of the tibia. In congenital tibial pseudoarthrosis, this often manifests as anterolateral movement or bowing of the tibia, which can significantly affect a patient's mobility and quality of life. The surgical procedure involves making a skin incision directly over the defect in the tibia, followed by careful dissection of the soft tissues to expose the underlying bone defect. The lesion is then excised to prepare the site for repair. Various techniques may be employed for the repair, including the placement of a compression device, a vascularized free fibular graft, autogenous bone grafting, or intramedullary rodding, among others. The choice of technique is determined by the specific characteristics of the defect and the surgeon's preference. After the repair is completed, the incisions are meticulously closed in layers to promote optimal healing. To ensure proper immobilization of the leg during the recovery process, a cast or splint may be applied as needed.
